Performing a visual inspection of a house in Nashville TN and came across this gem.
Homeowner complains of inability to regulate house temperature, odors, discomfort, and some sinus / health issues.
See photo below - the standard non existent vapor barrier, completely disconnected return plenum...within 8" of end of return plenum is a dead, decaying possum.
Wow. I am just stumbling upon this now in 2015. "Return Possum" caught my attention. Please tell us you fixed this.
Great photo -- beats most of the animal-related issues I've seen.
